This is a photo of the tank vent system for a 1980 SC. I had soaked/weeping hoses and all sorts of fumes in the cabin. I replaced the hoses (several hose clamps missing in this photo).
The smaller hose that snakes below the tank filler tube and under the fuse block goes into the fender wall. When I look for the exit on the other side, it seems to go into a "grayish" tank behind the headlight. Is that so?
I'm thinking that the vapors or over-fill or splash from a full tank go into the canister and get relieved into this tank?
Who knows what is really going on here? Is there a better way to vent fumes and overflow than the stock system?
Thanks for considering and replying.
